Aurum Resources (ASX:AUE) has returned ‘high-grade’ gold intersections outside the current mineral resource estimate (MRE) at its Boundiali Gold Project in Côte d’Ivoire.
Results from the BST1 deposit and BST2 prospect include 3m @ 80.09 grams per tonne gold (Au) from 66m, including 2m @ 117.73g/t Au, and 38m @ 4.20g/t Au from 65m, including 3m @ 30.52g/t Au.
At BST2, which has no defined mineral resource, drilling returned 3m @ 27.65g/t Au from 144m, including 1m @ 78.13g/t Au. The prospect lies about 18km northwest of BST1 and is defined by a 2km-long gold-in-soil anomaly.
BST2 was previously tested by 43 reverse circulation holes, most of which ended at around 50m. Only two exceeded 100m, leaving the prospect comparatively underexplored at depth.
Managing Director Dr Caigen Wang says the BST2 results point to a potential new source of ounces for Boundiali.
“At the BST2 prospect, which sits entirely outside the current mineral resource, today’s results support further growth potential, although more drilling will be required before it can be classified,” Wang says.
Aurum says the results also confirm mineralisation in areas of BST1 currently classified as inferred, with both systems remaining open along strike and at depth.
BST1 hosts 22 million tonnes (Mt) @ 0.8g/t Au for 570,000 ounces. As previously reported, the new results build on earlier drilling that supported further resource growth at Boundiali and will feed into the next MRE update, targeted for the end of Q3 2026.
Aurum says it plans to drill 100,000m at Boundiali and 30,000m at the Napié Gold Project during 2026, using its fleet of 16 company-owned diamond rigs. The company held $54.7 million in cash as at 30 June.
Following environmental approval in May, Aurum completed a Prefeasibility Study and established a maiden probable ore reserve of 42.1Mt @ 0.9g/t Au for 1.21 million ounces (Moz) in June. It is now working towards obtaining mining licences and expects to complete a Definitive Feasibility Study in late 2026.
Aurum Resources is a West Africa-focused gold explorer and developer with 4.38Moz of group resources, including 3.22Moz at Boundiali and 1.16Moz at Napié.
